Radiation hydrodynamics integrated in the code PLUTO
Stefan M. Kolb, Matthias Stute, Wilhelm Kley +1
The transport of energy through radiation is very important in many astrophysical phenomena. In dynamical problems the time-dependent equations of radiation hydrodynamics have to b…

Low-mass planets in nearly inviscid disks: Numerical treatment
Wilhelm Kley, Tobias W. A. Mueller, Stefan M. Kolb +2
Embedded planets disturb the density structure of the ambient disk and gravitational back-reaction will induce possibly a change in the planet's orbital elements. The accurate dete…

A conservative orbital advection scheme for simulations of magnetized shear flows with the PLUTO code
A. Mignone, M. Flock, M. Stute +2
Explicit numerical computations of super-fast differentially rotating disks are subject to the time-step constraint imposed by the Courant condition. When the bulk orbital velocity…
